Abstract: 1,040,794. Transistor pulse circuits. SUPERIOR ELECTRIC CO. April 23, 1964 [April 24, 1963], No. 16857/64. Heading H3T. [Also in Division G4] A step-by-step motor control circuit of the type in which stator windings A, A<SP>1</SP>, B, B<SP>1</SP> are sequentially energized in response to input pulses on one of leads 62, 63 in an appropriate order so as to step a permanent magnet rotor either clockwise or anti-clockwise respectively, comprises two transistor triggers 16, 36 which control the energization of the stator windings via transistor amplifiers 29, 30, 51, 52, and to which input pulses are selectively steered by diode gates 64, 65, 66, 67 and 72, 73, 74, 75. The circuit is so arranged that the four stator windings A, A<SP>1</SP>, B, B<SP>1</SP> are associated individually with the four transistors in the two triggers so that two windings are always energized. Also the two input leads 62, 63 are each associated with a group of four of the diode gates 64, 65, 66, 67 and 72, 73, 74, 75, respectively, which, in turn, are controlled, via their cathodes, by the four transistors in the two triggers. Thus in each group of four gates two are always open. In operation a negative input pulse on either of the two input leads 62, 63 passes through the two associated open gates to the bases of two of the four transistors of the two triggers, both of which it attempts to cut-off. However, the circuit is so arranged that one of these transistors will already be cut-off, so that the overall result of the input pulse is to change the state of one of the triggers. Diodes 56, 57, 58, 59, and a Zener diode 60, are provided to eliminate inductive spikes which might arise from the motor.

Patent GB-791197-A (GB)
Title: Improved process for preparing dicyclopentadienyl acids
Filed: 1956-06-06
Abstract: An alkali metal salt of a cyclopentadienyl dicarboxylic acid prepared by the process claimed in the parent Specification is treated with sufficient water in the presence of an acid to give an aqueous solution having a pH of not greater than 7.5, and the solution is then further acidified to convert the cyclopentadienyl salt to the corresponding acid.  Alternatively the solution of the alkali metal salt may be treated with sufficient acid to bring the pH of the aqueous solution to between 2 and 4 so as to precipitate all the dicarboxylic acid in one step.  The formation of the aqueous sodium salt solution takes place preferably at a pH of between 3 and 7.5 and the concentration of the salt in the resulting solution is preferably between 21 to 26 per cent by weight.  Suitable acids used to control pH are hydrochloric, sulphuric, phosphoric, sulphur dioxide or carbon dioxide under 1-75 atmospressure, and also organic acids, e.g. acetic, halogenated acetic acids, formic, and oxalic acids.  Suitable inert solvents are, e.g. xylene, benzene, methylcyclohexane, heptane and light naphthas.  The organic reaction mixture is preferably mixed with the required amount of anhydrous acid before the water is added, although the acid may be mixed together with the water, or sufficient acid may be added to the organic reaction mixture to both adjust the pH and precipitate the acid.  The quantity of acid used to yield a solution having pH 3 to 7.5 is between 3 and 14 equivalents per 100 mols. of the alkali metal used to form the salt, and the quantity of water to form the aqueous solution from 46-100 gms. per 100 gms. of initial dispersion.  Examples and tables are given illustrating the optimum amounts of acid to be used, type of acid to be used and temperature of reaction, and acids specified are dicyclopentadiene dicarboxylic acid and dimethyl dicyclopentadiene dicarboxylic acid.

Abstract: 612,967. Radio signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WELPLY, J. E. H. June 11, 1946, No. 17521. [Class 40 (v)] In a high-frequency send-receive radio communication system comprising a main control station, two or more subsidiary relay stations, and one or more mobile stations, the transmitter frequencies of the relay stations are made different and adjacent, the transmitter frequencies of the control station and the mobile stations and the receiver frequency of the relay stations are alike, and the receiver frequencies of the control and mobile stations are alike. The system enables uniform reception strength to be provided over a predetermined area, the arrangement being such that the plurality of transmitters at the relay stations are modulated simultaneously, but each transmitter operates at a different carrier frequency, the frequencies being selected so that they all lie within the band width of the mobile station receiver, but such that the intermodulation products fall outside the audio band width and thus do not serious interfere with reception. In the Figure, a relatively fixed control station CS is in land line or other communication with a control room CR. Fixed station CS comprises a transmitter TCS generating on a frequency of 80 mc/s. and a receiver RCS operating on a frequency of 96.3 mc/s. Two fixed subsidiary relay stations are shown at FS1, FS2, each comprising a receiver RFS1 operating at 80 mc/s., which drives a transmitter TFS1. The frequency of transmitter TFS1 is 96.3175 mc/s. and that of transmitter TFS2 is 96.2825 mc/s., the arrangement then being suitable for speech communication. Additional subsidiary relay stations may be provided, the transmitter frequencies being different but adjacent. MS is an example of one of the mobile stations, each of which comprises a receiver RMS operating at 96.3 mc/s. and a transmitter TMS operating at 80 mc/s. The communication paths for send and receive are shown by full and dotted lines.

IPC: C13B25/00
Filed: 1928-06-18
Abstract: 292,915. Boulogne, B. June 25, 1927, [Convention date]. Progressive evaporators.-In evaporation plants used e.g. in sugar factories in which separate evaporation elements are connected by U-shaped conduits 7 arranged so that the difference in level of the liquid is the two limbs of the U compensates for the difference in pressure in the elements, provision is made whereby liquid on its way from one evaporation element to another is cooled to prevent ebullition in the conduit. This cooling may be effected by the intensive mixing of the incoming liquid with the liquid already in the conduit as by providing an enlargement in the conduit, or by circulating relatively cool fluid through tubes 5, 6, Fig. 1, or by jacketing the incoming fluid with a current of cooler fluid as shown in the evaporation element 4. A weighted valve 8 may be used to aid in compensating for pressure differences. When a simple enlargement of the conduit is used a float valve may be provided in the enlargement.
